Warwick Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Warwick's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Warwick, RI — 69 swim days a yearThe bar compresses Warwick's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the May 3–May 24 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 8. Wherever the today marker sits, the nearest color change is your next appointment.
The Warwick pool calendar
Opening — target May 10
Target May 10; the practical window runs May 3–May 24, and the 7-day mean crosses the 61°F threshold around May 24. Cold-water starts are the cheap ones.
Closing — deadline October 8
Hold the cover until September 28, then winterize by October 8, a week ahead of the October 30 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Warwick's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 32° | 30° | 36° | 45° | 55° | 64° | 72° | 74° | 70° | 60° | 49° | 40° |
The curve peaks near 75°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Providence's pool season and Cranston's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Rhode Island season index.
Warwick pool season FAQ
When should I open my pool in Warwick, RI?
Open by May 10 — the model places Warwick's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Warwick opening guide has the 12-step sequence.
When should I close my pool in Warwick?
Close by October 8: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Warwick closing guide sequences the work backward from that date.
How long is the swim season in Warwick?
Warwick averages 69 days a year with normal highs of 80°F or better — right on the statewide median. The Rhode Island season index ranks all 4 covered cities by the same metric.
How warm does pool water get in Warwick?
An unheated pool near Warwick typically peaks around 75°F in high summer and bottoms out near 30°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
